the body 10 is a threaded opening in which a combined cap or sleeve 17is secured. the cap having a seat 18 in its lower end and a ateralrecess 19 in its upper cnd. The combined sleeve and cap 17 is formedwith a central bore to receive a stem 20 having a collar 21 at its lowerend to engage in the seat 18 and with a stud 22 to engage in the socket16. The socket as indicatul in Fig. 3 extends to one side of the centerof the valve and the pin 22 is likewise at one side of the center of thestem. so that when the stem is oscillated the valve will he oscillatedtherewith and caused to hear against the seat 13 or to he moved to oneside of the same. as will be obvious. Thus when the stem 20 is in oneposition. the valve will he closed and when the stem is in its otherposition the valve will he opened. The recess 19 is slightly greaterthan one-fourth of a circle, and secured in.the stem 20 and projectingthrough the recess is a stop-pin .23. the pin thus being adaitcd to engae.

alternately against the end walls of tie recess. By this arrangementwhen the stem is oscillated in one direction the pin hears against oneend wall of the recess and against the other end wall of the recess whenmoved to its other position.

Thus
